Prince Harry and Cressida Bonas in Their First Public Event Together

At the first official event the couple have attended together, Prince Harry and Cressida Bonas looked cozy and comfortable as they sat hip to hip at We Day in London today. We Day, organized by international charity Free The Children, is designed to motivate and inspire young people to find their passion and stimulate social change. Prince Harry spoke on stage to the 12,000 participants, mobilizing the eager youths about social change. “Personally, I think it’s the coolest thing in the world,” said Prince Harry, while Cressida heckled and cajoled him from her V.I.P. sideline seat, alongside her half-sister, Isabella Calthorpe. Sitting a row above Princess Beatrice and her boyfriend, Dave Clark, Cressy seemed to be getting into the electric energy of the day. Before Prince Harry found his seat next to her, we spotted her opting for a quick hairstyle swap, as she plaited her hair into two pigtail braids before joining the rest of the crowd in the patented We Day dance.

Award-winning actor Clive Owen, former Vice President Al Gore, and Malala Yousafzai also spoke at the event.

Although an inside source had told us Prince Harry had made it known he had no interest chatting with or meeting the event’s other celebrity guests, we spotted him having a few words with Clive Owen and Al Gore, among others. To give him some credit instead, Harry reportedly had explained he only wanted to engage with the youth participants. But decoding his behavior from the day, we’d say he really only wanted to engage with one Ms. Cressida Bonas.
